The primary soap receptacle is located below the lavatory plate, a discharge nozzle being disposed above the plate together with an 'operating plunger for a pump valve andconduit elements which operativelycommunicate with the interior of the soap receptacle. The invention will be 1 described with reference to the accompanying drawings in which Fig.1 is a sectional elevation of an embodiment of the invention, and Fig. 2 is an enlarged section on the line 2 2 Fig. 1.

In the drawings A. indicates the main casing of the device, the casing being formed with a depending tubular member 1 at the top of which the casing is outwardly flared providing an annular shoulder 2. The casing is also formed with a nozzle .3. The casing is applied by passing the tubular extension 1 through an opening in the lavatory top 1 after which nut 5 is turned upward on the threaded tubular member to clamp the device in position. A washer 6 may be interposed between the. lavatory plate and nut 5. The bore of tubular member 1 is slightly reduced towards its lower end and into said reduced section is fitted the upper end of a tube 7 the tube being held in place by .a set screw 8. The end of tube 7 is threaded to receive a pump casing 9.

Extending centrally of tubular member 1 and tube 7 is'an operating rod 10. The rod at its lower end enters pump casing 9. Within the casing the rod is flanged at 11 to serve as an abutment or stop for a washer 12, the latter being held in place by a shouldered thumb nut 13 threaded on a reduced section V of the rod. below flange 11. Washer 12 en gages the walls of the annular bore 9a: of the valve casing, the base of the bore being narrowed and communicating with a ball-hold ing chamber 14, enclosing aball valve 15, the

. ball normally shutting ofi an air inlet 16. Within bore 900 is aspring 16 which, engages thumb nut 13 and serves to maintain rod 10 normally in an upper position.

Lgr-In theLoperationofthe device, downward movement of plunger comprising elements 17 and-.19,-'guided by 'beaiing plug 18 threaded in casing A, willithrough rod 10 impart: a

downward and assertive movement to the pump against the tension of spring 16. As" explained above the pump casing'anddeeng ged .byiga" plun -er stem ll 7 pendent tubular member 1 will be disposed within a liquid soap-containing receptacle. Soap which has entered bore 9% by a previous upward or suction movement of the pump will in said operative movement of the pump be forced through duct 20 and'thence upwardly through tube 21 for discharge through nozzle 3.

Onebf the primary advantages of the de-'=-L vice resides in the simplicity of construction and lightness of. operation. The pump is, formed quite independently of the nozzle, and the nozzle top forms the main casing of the device so that a very rigid connection to. the lavatory top is provided. The integral depending tubular member of the casing A receives the nut 5 by means of which the device is clamped to the lavatory top. The tubular member 21, by means of which the soap A passes vfrom the pump to the nozzle, can be detached for cleaning, and all of the parts may very quickly be disassembled and reassembled for cleaning, repair or replacement.

Having described my invention what I claim and desire tosecure by Letters Patent is as follows: it being understood'that various modifications may be made in the form and arrangement of the embodiment shown. Forexample, the soap container 21: may be 1 supported in any suitable manner. In the present instance, however, the container 21: is' shown as having a cap 22 secured to a threaded neck member 23, the latter being threaded upon tubular extension 10f the faucetkcasing.
